SHOE-SOLE Specification of Letters Patent.

Patented Jan. l2, lOQ.

Application led August 31, 1908. Serial No. 450,979.

T o all whom t may concern:

Beit known that l, CHARLES K. SHAROOD, a citizen of the United States,residing at St. Paul, in the county of Ramsey and State of Minnesota,have invented a new and useful Shoe-Sole, of which the following is aspecification.

The objects of the invention are, the provision in a merchantable formof a device of the class described, which shall be inexpensive tomanufacture; the provision of a shoesole which shall give ampleprotection to the foot of the wearer; the provision in a novel form, ofan upstanding peripheral rib Whereunto the inseam may be stitched; otherobjects and novel features of construction being disclosed as thedescription of the invention progresses.

The invention consists in the novel construction and arrangement ofparts hereinafter described, delineated in the accompanying drawings,and particularly pointed out in the appended claims, it being understoodthat various changes in the form, proportions, size and minor details ofthe structure may be made, without departing from the spirit orsacrificing any of the advantages of the invention.

Similar numerals of reference are employed to indicate correspondingparts throughout the several figures of the drawings.

In the accompanying drawings, Figure l shows the invention in verticallongitudinal section; Fig. 2 is a top plan; Fig. 3 is a verticaltransverse section on the line A-B, of Fig. 2 enlarged, that theconstruction may be more readily perceived.

In carrying out the invention, a thin lower layer of leather l isprovided upon which is superposed a layer of heat-insulating material 2,preferably cork, the lower side of the layer 2 being covered with alayer of cloth 3, preferably cemented to the layer 2, the thin lowerlayer of leather l being stitched to the layers above it as shown at 10.Between the layers 1 and 3 is inter,- posed a heel-piece 4, preferablycemented in place, conforming to the periphery of the sole andterminating at the rear of the instep in a thinned edge 5 disposedtransversely to the longer axis of the sole as shown by the dotted line1l in Fig. 2.

Superposed upon the layer of heatinsulat ing material 2 and preferablystitched at 7 to the layers 2 and 3, is the up er layer of leather 6.rlhe stitching 7 W ereby the layer 6 is attached to those beneath it,follows the periphery of the layer 6 at a slight distance therefrom, asshown in Fig. 3. The outer edge of the upper layer of leather 6 thusleft free, is flexed to form the upstandino rib 9, lying within theperiphery of the `ljayer of heat-insulating material 2. A layer oftextile material 8 covers the layer 6, and the edges of the layer S arestitched through the layer of heatdnsulating material 2 and the layer 3,between the upstanding rib 9 and the periphery of the layer 2, suchstitching being indicated by the numeral 12.

ln forming the upstanding rib 9, to which the inseam is commonly sewed,the usual practice has been to employ a piece of soleleather to form thelayer 6 slit the layer peripherally near its edge at an acute angle tothe plane of the layer 6, raise the edge of the slit and sew the inseamthereto. This process results in weakening the layer 6, and the rib thusformed gives but an insecure place of attachment, difficulties which areobviated in the sole of my invention.

The use of the heel iece 4 furnishes a firm foundation for the hee intowhich attaching nails may be clenched, and the general construction ofthe sole, comprising a layer of heat-insulating material interposedbetween layers of leather results in a light and ilexible sole, capableof resisting dampness and cold.

l-laving thus described the invention what is claimed as new is.

1. In a device of the class described, a layer of relatively stillmaterial; snperposed thereon, a layer of relatively flexible materialhaving its edges upstanding within the periphery of the layer eneath it;a second layer of relatively flexible material superosed upon the firstand having its edges stitched to the layer of stiff material, betweenthe upstanding edges of the iirst layer of flexible material and theperiphery of the layer of still material.

2. A shoe sole comprising a lower layer of leather, a layer ofheatinsulating material superposed upon the lower layer of leather;interposed between the lower layer of leather and the layer ofheat-insulating material, a heel-piece conforming to the periphery ofthe sole and terminating at the rear ofthe instep in a thinned edge;superposed upon the layer of heat-insulating material another layer ofleather having its edges upstanding within the peri hery of the layer ofheat-insulating materia a layer of textile material covering the upperlaye-r` of leather; and` edges stitched to thelayers benethvit; bei..

tween the u standing edges of the upper layer of leat er and theperiphery of the layer of heat-insulating material.

3. A shoe sole comprising a lower layer of; leather; a layer of corksuperposed upon the lower layer of leather; interposed between the lowerlayer of leather and the layer' of cork, a heelieee conforming to theperiphery ofthe so e and terminating at the rear of the instep in athinned edge; superposed upon the layer of cork an inner layer ofleather .having its edges upstanding within the periphery of the layerof cork; a layer of ytextile material covering the upper layer ofleather, and having its edges stitched to the layers beneath it, betweenthe upstanding edges of the upper layer of leather and the peripheryofthe layer of cork.

4. A shoe-sole comprising a lower layerof leather; a layer ofheat-insulating material superposed upon the lower layer of leather;superposed upon the layer of heat-insulating material an inner layer ofleather having its --thenlayer heat -insulating material; a

layer of leather, and having its edges stitched tothe layers beneath it,between the upstanding edges of the upper layer of leather and theperiphery of the layer of heat-insulating materia 5. Asho'eesolecomprising a lower layer of leather; a layer of corksuperposed upon the lower layer of leather; superposed upon the layer oftcork, an up er layer of leather having its edges upst ancling withintheperiphery of the layer of cork; a layer of textile material coveringthe upper layer of leather, and having its edges stitched to the layersbeneath 1t, between the upstanding edges of of the layer of' cork.

In testimony that I claim the foregoing as 'my own,- l have heretoaflixed my signature in the presence of two witnesses.
